Receiver for securing a firearm

ABSTRACT

A barrel of a firearm is held by a firearm restraint housing having a pair of spaced apart rotors rotatably mounted and contoured for receiving the barrel of the firearm therebetween. A slide member is positionable in interference with rotation of the rotors in its first position and in non-interference with rotation of the rotors in its second position. The position of the slide is determined electromechanically or by a hand key operated lock. The rotors are contoured so that withdrawal of the firearm barrel counter-rotates them into a barrel receiving attitude, and further, placement of the barrel between the rotors forces them into counter-rotation for locking around the barrel.

Sanchez, WO 9811399, An electronically activated holster that releasably secures a weapon to the holster. Locking mechanism releases the weapon upon receiving an electrical signal generated when certain conditions are present. These predetermined conditions are selected by a user and these inputs can be sensed with photosensitive devices and attached to the holster that detect bar codes on a user's hand or glove so that a predetermined pattern can be read and conveyed to a control circuit, such as a central processing unit. In turn, control circuit records the event and causes the locking mechanism to release weapon if the necessary conditions are present. Alternatively, an ultrasonic transmitter can be worn by a user in a wristband and a cooperative receiver on the holster designed to be activated when a predetermined proximity is achieved. An alarm output is provided to visually or audibly broadcast a violated condition. Optionally, a transmitter is incorporated to the holster to broadcast the condition of the alarm and a remotely placed receiver is used to monitor the broadcast. Another input is supplied by a general positioning system that ascertains the location of the holster at selected times, stores it, and/or broadcasts it. An input/output port permits exchange of data and instructions to and from the control circuit.

Our prior art search with abstracts described above teaches: a gun holding device, a weapon holster, an enclosed gun lock, a gun rack for police car, a vehicle mounted locking firearm support, a firearm safeguard device, a firearm support, a tamper-resistant safety gun lock, a weapon trigger guard apparatus, an all terrain vehicle rear deck bracket assembly, a vehicle partition, and an electronically activated holster. Thus, the prior art shows that it is well known to lock firearms and such locking devices include sliding, rotating and closure mechanisms capable of securing firearms by their several mechanisms. However, the prior art fails to teach a barrel gripping apparatus having opposing rotors with concave contours for placement of the barrel, nor a linear slide mechanism for releasing the rotors for barrel removal. The present invention fulfills these needs and provides further related advantages as described in the following summary.

SUMMARY OF THE INVENTION

The present invention teaches certain benefits in construction and use which give rise to the objectives described below.

In a best mode preferred embodiment of the present invention, a barrel of a firearm is held by a firearm restraint housing having a pair of spaced apart rotors rotatably mounted and contoured for receiving the barrel of the firearm therebetween. A slide member within the housing is positionable in interference with rotation of the rotors in its first position and in non-interference with rotation of the rotors in its second position. The position of the slide is determined electromechanically or by a hand key operated lock. The rotors are contoured so that, when unlocked, withdrawal of the firearm barrel counter-rotates them into a barrel receiving attitude. Placement of the barrel between the rotors forces them into counter-rotation for locking around the barrel. The rotors are double sided for two ranges of barrel diameter and a release pin is positioned for reversal of the rotors. The housing may provide track mounting. A transverse orientation of the actuating solenoid provides for a highly compact unit and prevents external magnet actuation. A non-magnetic push rod prevents external magnet actuation.

A primary objective of one embodiment of the present invention is to provide an apparatus and method of use of such apparatus that yields advantages not taught by the prior art.

Another objective is to assure that an embodiment of the invention is capable of locking a firearm by merely inserting the barrel of the firearm into the invention.

A further objective is to assure that an embodiment of the invention is capable of releasing the barrel by electromagnetic means.

A still further objective is to assure that an embodiment of the invention is capable of adaptation to more than one barrel size.

Other features and advantages of the embodiments of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of at least one of the possible embodiments of the invention.

DETAILED DESCRIPTION OF THE INVENTION

The above described drawing figures illustrate the present invention in at least one of its preferred, best mode embodiments, which is further defined in detail in the following description. Those having ordinary skill in the art may be able to make alterations and modifications in the present invention without departing from its spirit and scope. Therefore, it must be understood that the illustrated embodiments have been set forth only for the purposes of example and that they should not be taken as limiting the invention as defined in the following.

In the best mode embodiment of the present invention a housing 10 supports, a pair of spaced apart rotors 20 which are rotationally mounted in the housing 10 at bushings 11, and are contoured for receiving a firearm barrel 30 between them as shown in FIG. 1 at the left. As seen in FIGS. 3 and 4, a slide 60 is a positionable member and as such is positionable in interference with rotation of the rotors 20 in a first position (FIG. 4), and in non-interference with rotation of the rotors 20 in a second position (FIG. 3) and this enablement will be further described in detail in the following. The positionable member (slide 60) may be any form of positionable element and is not restricted in the scope of this invention to a sliding element. However, the positionable member will be referred to as “slide 60” herein for convenience. The rotors 20 are contoured so that withdrawal of the firearm barrel 30 from between the rotors 20 counter-rotates the rotors 20 into a barrel receiving attitude 50 which is shown in FIG. 3, and further, so that placement of the barrel 30 between the rotors 20, with the rotors 20 in the barrel receiving attitude 50, counter-rotates the rotors 20 into a barrel locking attitude 50′ (FIG. 4).

Preferably, the housing 10 comprises two housing portions 12 and 14 joined by fasteners 15 (FIG. 2) at medial abutment surfaces 16 as best seen in FIG. 2. Preferably, the housing 10 provides a housing notch 18 and contoured elements of the rotors 20 extend into the notch 18 from opposing sides of the housing notch 18 as is clearly shown in FIGS. 3 and 4. The contoured elements of the rotors 20 comprise concave surfaces 22 and preferably comprise two of such surfaces on each rotor 20 so as to accommodate barrels 30 of two different diameter ranges. As seen in FIGS. 3 and 4, the rotors 20 may be aligned so that a larger diameter pair of the concave surfaces 22 are mutually facing for receiving a barrel 30 of a corresponding diameter range, and alternatively a smaller diameter pair of the concave surfaces 22, shown in FIGS. 3 and 4 as facing away from each other may be rotated by 180° to mutually face each other across the notch 18 for correspondingly smaller diameter barrels 30. Thus, as shown, the rotors 20 preferably each have two opposing of the concave surfaces 22 located on opposite sides of the rotor 20.

Preferably, the rotors 20 each provide two first rotor grooves 24 each positionally associated with one of the concave surfaces 22. Grooves 24 enable the rotors 20 to be locked at preferred rotational positions as will be described. See FIGS. 3 and 4. Preferably, a slide 60 provides a pair of slide grooves 62, and the housing 10 provides a pair of pin grooves 18; such that with the slide 60 positioned in a first slide position (FIG. 4), the slide grooves 62 are not aligned with the pin grooves 18, while with the slide 60 moved to a second slide position (FIG. 3), the slide grooves 62 are aligned with the pin grooves 18.

A pair of locking pins 70 are held within the pin grooves 18 of the housing 10. The locking pins 70 engage with the first rotor grooves 24 for locking the rotors 20 in the barrel locking attitude 50′ (FIG. 4) when the slide grooves 62 are non-aligned with the locking pins 70. The pin grooves 18 are located and sized so as to allow release of the locking pins 70 from the first rotor grooves 24 when the slide grooves 62 are aligned with the locking pins 70, as shown in FIG. 3.

Preferably, the rotors 20 each provide a second rotor groove 26 which is aligned with the locking pins 70 when the rotors 20 are in the barrel receiving attitude 50 (FIG. 3). The second grooves 26 are shallow so as to function as detents for capturing and holding the rotors 20 and biasing them to stay in the receiving attitude, but also allowing the rotors to move out of the receiving attitude when pressed by a barrel 30, so as to move to the barrel locking attitude (FIG. 4).

The apparatus preferably uses an electromechanical device 80, such as an electrical solenoid actuator, well known in the art, to engage the slide 60 in moving it from its locking (default) position, shown in FIG. 4 to its unlocking position, shown in FIG. 3. When electric current is applied to the electomechanical device 80 through feed wire 85, a ferromagnetic actuator 82 is moved to the left in the figures against a biasing expansion spring 90, thereby aligning the slide grooves 62 with the locking pins 70. This enables the locking pins 70 to move out of the first rotor grooves 24 so that the rotors 20 are free to rotate into the barrel receiving attitude shown in FIG. 3 normally by the force that the barrel 30 exerts on the rotors 20 at their outer lips 27 (FIG. 4). When the electrical current is cancelled, the expansion spring 90 is not able to move the slide 60 and the actuator 82 back to their rest positions because the shallow second grooves 26 in rotors 20 force the locking pins 70 into slide grooves 62 which holds the slide 60 from moving. However, when barrel 30 is again pressed into the notch space between rotors 20, its force against inner lips 27′ (FIG. 4), causes the rotors 20 to rotate until the locking pins 70 engage rotor first grooves 24 which are deeper grooves than rotor second grooves 26. This enables locking pins 70 to move out of slide grooves 62 and permits the slide 60 to move back to its original, default position. Clearly pin grooves 18 are adapted by being elongated to allow locking pins 70 to have a small amount of lateral movement.

Preferably, the housing 10 provides engagement cavities for receiving mounting hardware 110 as shown in FIG. 2. The mounting hardware 110 may provide a threaded hole 112 for receiving a threaded fastener (screw) or may be any other type or kind of mounting device.

Alternately, a mechanical device, such as the rotational key lock 100 shown in FIG. 2 may be positioned as shown in the figures for mechanically pushing, using pusher 102, against one end of the slide 60. The key lock 100 is turned with one hand while the barrel 30 is withdrawn from the apparatus or inserted into the apparatus with the other hand. As in the above description, while holding the slide in the unlocked position with the key lock, removal of the barrel 30 rotates the rotors 20 to the unlocked attitude 50 and they remain in that state until the barrel is again replaced.

The enablements described in detail above are considered novel over the prior art of record and are considered critical to the operation of at least one aspect of one best mode embodiment of the instant invention and to the achievement of the above described objectives. The words used in this specification to describe the instant embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification: structure, material or acts beyond the scope of the commonly defined meanings.
